Title: Inscribed meshing planet gear structure
Inventor: MARUO TOYOSHI
IPC: F16H55/06
Filed: 1990-05-22
Abstract: PURPOSE:To avoid seizure and wear so as to transmit high torque by integrally molding an external or internal gear of a metal dust sintered material, impregnated with oil, to a part which constitutes teeth of the gear. CONSTITUTION:A temperature of sliding surfaces is increased by a relative slip generated when an external gear 151 and an internal gear 20 are meshed with each other, and as a result, impregnation oil oozes out, so that seizure and wear can be avoided even without rotatable pin-constitution of a tooth part 151A or 20A in both the gear 151 and the internal gear 20. Since power is transmitted basically by an inscribed meshing planet gear structure, large reduction ratio is obtained even by a small size. Further, friction can be less decreased in cooperation with a small peripheral speed of the gear because it is in small size, and in addition, metal is used in a gear member even in its small size, so that a very high output is obtained in the structure as compared with that of using plastic or the like for the gear member.

Filed: 1984-06-28
Abstract: PURPOSE:To permit to secure averaged electric power demand by a method wherein an operating means is provided to move the peak of electric power of the electric water heater toward the center of a specified time band. CONSTITUTION:In case the conduction time for a heater is estimated to become shorter than the specified time band, a conduction beginning time is delayed than the beginning of the specified time band so that a non-conduction time is distributed to the foreward and afterward of the conduction time in the specified conduction time. The operating means 6 reads out a heat-up temperature, corresponding to a feed water temperature, from a hot-water temperature control pattern memorized in second memory 11 and a time shift, corresponding to the feed water temperature, the heat-up temperature and a remaining hot-water amount, from third memory 12 while a signal is sent to an output means 15 immediately to control the conduction of the heater 16 when the time shift is zero. When there is the time shift, a timer accommodated in the operating means 6 is driven, the signal is sent to the output means 15 after the time shift elapsed and, thus, the conduction of the heater 16 is controlled. When the temperature of hot-water 20 is detected by the temperature sensor 1 and the hot-water 20 is heated up to the heat-up temperature thereof, the conduction of the heater 16 is interrupted.

IPC: F04C18/02
Filed: 1984-06-27
Abstract: PURPOSE:To reduce the input and prevent the seizure between each slidable surface of an annular body and a movable element by installing a thrust-force reducing mechanism having the specific constitution onto the outside-surface side of a movable element and sufficiently reducing the thrust force applied onto the movable element. CONSTITUTION:The annular space Q which is surrounded by the annular body 60 of a thrust-force reducing mechanism 59, inner and outer sealing rings 62 and 63, and an end plate 33 and communicates to a compression chamber P through holes 66 and 67 is formed as the surface on the contact side of the annular body 60 with a movable element 22, and has the outside surface of the movable element 22 as a part. Therefore, the force towards a fixed element 21 acts onto the movable element 22. Therefore, the thrust force departing from the fixed element 1 which is generated by the above-described force is markedly reduced. Since a hole 117 for splashing a portion of the lubricating oil pumped-up through a hole towards the undersurface of the end plate 33 is formed onto the outside surface of the movable element 22, and oil grooves 65a and 65b are formed onto the slidable surface of the annular body 60 with the movable element 22, the generation of seizure between the both can be certainly prevented.

Filed: 1986-06-06
Abstract: PURPOSE:To obtain a counter circuit outputting incremental/ decremental count with a small delay by outputting the least significant bit of the incremental count as it is and outputting other bits while a negative logic value is retarded. CONSTITUTION:An output A of an incremental counter circuit 20 consists of n-set of bits ai (i=0,1,2$...,n-1) and the bits a1-an-1 except the least significant bit are fed respectively to 1-bit shift circuits 11-i (i=1, 2, ..., n-1) respectively, which retard the inputted bit ai respectively by a unit time and supply the result to a NOT circuit 10-i. A clock pulse from a clock terminal 30 is fed to the incremental counter circuit 20 and the 1-bit shift circuit 11-i. The least significant bit a0 of the output A and the output of the NOT circuit 10-i are respectively a bit b0 and b1-bn-1 of an output B. Thus, the output B of decremental count is obtained synchronously with the output A of the incremental counter.

Title: Saw tooth deflection current generating circuit
Inventor: SHIMANUKI SHINJI
IPC: H03K4/08
Filed: 1983-07-20
Abstract: PURPOSE:To decrease the power consumption of an output transistor (TR) widely by flowing the discharge current of the capacity for correction to a separately installed switching element without passing the current to the horizontal output TR. CONSTITUTION:The switching element 12 is connected in parallel to a parallel circuit formed by a capacitor for correction CA and diode D2 and serially to the horizontal output the TR Q1. Then TR Q1 and element 12 are synchronized and switched and controlled by the horizontal drive pulse generating circuit 11. For this reason, when the TR Q1 and the element 12 are changed to the connection condition, the discharge current from the capacitor CA is not piled up to the collector current of TR Q1 and the collector current will not rise up in a spike state. Since the discharge current is not supplied to the TR Q, the rising time, falling time and also base accumulation time of the TR Q1 decrease. Therefore, the power consumption of the TR Q1 is changed to ''OFF'' state can be widely decreased.

Abstract: PURPOSE:To enable to form an SiO2 film, having no deterioration in characteristics such as insulating property and the like, on the surface of silicon without performing an excessive heating and the like by a method wherein, after a silicon oxide film is formed on the surface of a silicon substrate, a sintering is performed at a specific temperature. CONSTITUTION:After a silicon oxide film is formed on the surface of a silicon substrate by contacting the processing solution of supersaturated silicon oxide formed by adding boracic acid into a hydrofluosilicic acid aqueous solution wherein silicon oxide is dissolved, a sintering is performed at 400-800 deg.C. Pertaining to the hydrofluosilicic acid aqueous solution, one which is formed in 1-2mol/l concentration by diluting with water after silicon oxide is saturated in the hydrofluosilicic acid aqueous solution of 2mol/l concentration or above is considered desirable because it has a high film forming speed. As to the quantity of boracic acid to be added, 1.2X10<-2>-40X10<-2>mol to the hydrofluosilicic acid in hydrofluosilicic acid aqueous solution of 1mol is desirable to obtain a homogeneous film at a high speed. Also, a sintering at the temperature higher than 800 deg.C leads to the cause of generation of impurity diffusion in a semiconductor element, and the high denseness of film is not conspicuous at the temperature lower than 400 deg.C.

Title: Production of patterned dimming material
Inventor: YAMAKIDO MASAYOSHI
IPC: G02F1/1333
Filed: 1990-05-23
Abstract: PURPOSE:To display a distinct pattern which has a good contrast between a cloudy area and a transparent area for a long period and is free from unevenness at the time of no application of a voltage by applying the voltage between the transparent electrodes of a dimming material to make a liquid crystal layer transparent and partially irradiating the dimming material with light in this state and irradiating the dimming material thereafter without applying the voltage between transparent electrodes. CONSTITUTION:An AC voltage is applied between upper and lower transparent electrodes 2a and 2b of the dimming material to change a liquid crystal layer 1 from the cloudy state to the transparent state, and in this state, while superposing a mask plate 10 where a cut pattern is formed on one face of the dimming material, the liquid crystal layer is partially irradiated through the mask plate 10 by a light source 11. Then, optical reactive matters included in a resin matrix act on liquid crystal molecules, and they are orientated in the direction of the electric field and are restrained (fixed). Therefore, the liquid crystal layer is not returned to the cloudy state though the voltage non-application state is set, and a transparent area 4 which is always transparent is formed in the liquid crystal layer 1. Thereafter, an unirradiated part is irradiated by the light source 11. Thus, a cloudy area 40 as the unirradiated part of the liquid crystal layer 1 is fixed.
